Now look for elastic fibers in the tunica media (middle layer) of the aorta wall (slide 100) (Fig. 5-13).

• Their ultrastructural appearance is found in Fig. 5-14.
• On slide 92 examine the internal and external elastic laminae on either side of the tunica media (Fig. 11-8).

What cell type(s) produces elastic fibers and how is this type of CT functionally different from "dense" CT?

Examine slides 92 and 45 for examples of white adipose tissue (Fig. 6-1).

In the living condition, what is contained in the wide empty spaces of this tissue?

Compare the differences between white and brown (photo to the right) adipose tissue (Figs. 6-1 and 6-4).

What are the structural differences between white and brown adipose tissue?

Where is brown adipose tissue usually found in humans and why?

How do the structural features of brown fat (and its differences from white adipose tissue) facilitate its major function?

Next comes cartilage and bone.
